First thing....don't quit....every new student has been where you are. Afraid to ask a lady to dance because she is a more advanced dancer that you are and you don't want to do the same moves over and over...we all get that...
second....many (not all) lady dancers really don't know their own steps...they rely way too much on the men do push or pull them (literally) in the right place....dancing should flow it shouldn't be a physical contest to get the lady where she needs to go. There's a woman at the studio I attend to admitted that to me one day. She seems to move very well on the floor and she and I were just chatting one day and she mentioned she can follow very well, but she can't dance...there's a difference...point is, don't be afraid and don't think that just because a woman can follow she's a good dancer.
Hang in there...perhaps the studio you attend is the wrong studio for you. Let's all be honest, we stay at our studios because we fit in...we have friends there, we feel comfortable there, etc...when I first started taking lessons, I remember walking in the studio the very first time and I was scared to death....no reason to be that way, but I was. After a shirt while, I became comfortable with all the people and now it's like walking into a friend's house....point is, if you feel odd at your current studio, perhaps it's because you don't interact with the people very well, and you might want to check out other studios.
Just a thought.
